One of your instincts is to hold out & do nothing & hope that they sort there shiiit out & pay u the monies owed. The problem is for you, is can you as a company survive the loss of the money owed, maybe but whats certain is you prob would not survive that & the loss of you gear,which tbh will be held up on site for months while the powers that be decide who what its worth & who owns it & all the moaning & tears will not allow them to release it legally.i actually know of a case where the recievers successfully prosecuted the scaffold company for "stealing"back its own materials for several thousand pounds which it then put into the kitty for paying back the creditors to which the scaffold company got 5p in the £1 of the outstanding invoice, the problem was they owed £15k of invoiceing but the stock was worth over £50k & although they got it back eventually it was too late & they also went down.
my advise to you,which i've done before it get the kit down,&back in ur racks as quick as possible,then just get in line & fight for your money.at least with ur gear back it can either earn for you or at worse be sold to lower ur loss...if you choose to ride the storm @ the very least pull all the brds off only to replace them or do other work on site with an advance payment, they will allways tell you that everthings ok & not too worry or maybe even that another company/receivers need the project finished & sold so they can get the monies in to lower the losses & pay you. But you will allways be at the back off the queue after the receivers fees,solicitors & legal fees, bank loans,material creditors & finally labour creditors.
good luck phil what ever you choose.
